I have a pnp modem "SupraExpress 56i Sp V.90" that works fine with a
kernel from Aug 22. Here is an excerpt from a successful boot:

Todays GENERIC kernel hangs after correctly detecting sio2, with no keyboard
input, reboot necessary, yada yada yada.
Disabling sio2 from the config menu will let it boot. Here's a
verbose log of todays GENERIC kernel with sio2 disabled:

Any ideas? BTW, here's a pnpinfo -v:
